[WD18] - Copy the window image

Startbeitrag von JP am 08.09.2013 14:35

Hi All,

I am looking to copy the window image. I have found the function dCopyWindowImage() which does work fine. However, this copies the window image including borders and title bar. How can I copy only the inner contents of the window, without borders or title bar, to an image variable?

Thanks

Hello JP

There was a much earlier example in V9 that I can't find now but it used dCopyBlt()
It may give you what you need.



IF GScrnCapBorder = True

	//Include Borders

  dCopyBlt(copyScreen,LImageDest,copySrcCopy,WinOutXPos(),WinOutYPos(),WinOutHeight(),WinOutWidth())

 ELSE

	//exclude borders

  dCopyBlt(copyScreen,LImageDest,copySrcCopy,WinInXPos(),WinInYPos(),WinInHeight()+2,WinInWidth()+2)

 END



// Save to the JPGP format			 

dSaveImageJPEG(LImageDest,GScrnCapJPG,100)

dEndDrawing(LImageDest)		// Free the size taken in memory

Hi Al,

Thanks for the suggestion. I'm using WD18 and it says that the dCopyBlt function is deprecated. When I try to use it, it fails to create the new image - it does not generate an error but also does not copy the source image even if I let the additional parameters be defaulted i.e. just make a coipy of the source image.

WD suggest using dCopy() but that also is not recognized in the editor. I try and use the French variation dCopie() which is recognized in the editor but again it does not copy the source image.

I aslo tried dCopyScreenImage() which works but you get the whole screen, obviously.

I tried dCopyWindowImage() and that works but you get the borders and title and I cant see how to remove them from the final image to save.

Hi Al,

Thanks to you I found a solution using dCopyScreenImage() combined with the parameters you used in your example for x,y,width, and height coordinates of the window.



SourceImage is Image

SourceImage =  dCopyScreenImage( WinInXPos(), WinInYPos(), WinInWidth() , WinInHeight() )

Thanks Al!

Hello JP

It all comes around - you have now helped me solve a problem I would have had when I converted my older projects to V18
